"It was like an ocean all around. That place always gets flooded, but this time was the worst."

TETERBORO — Victims of the flooding in Moonachie and Little Ferry are arriving by the busload at the Teterboro campus of Bergen County Technical High School.

There are between 300 and 400 displaced people at the temporary shelter, Bergen OEM chief Lt. Dwane Razetti said, though the actual flooding may have displaced more than 1,000.

State police, local fire departments and Bergen County Police Department search and rescue teams are still going door to door in flooded areas as evacuees continue to pour in.

"We're asking everyone to leave," Razetti said. "Depending on a case-by-case basis, some people may be more urged to leave."

Authorities were using the school as a reception center, shipping evacuees there to reunite with their families before taking them to relatives' homes or shelters. The county has set up shelters at Bergen Community College and the Lyndhurst senior center as well.

Franklyn Rivera was one of the evacuees, rescued from his trailer near the Teterboro airport by the national guard. He arrived at the shelter at about 11 a.m.

"It was like an ocean all around," he said. "That place always gets flooded, but this time was the worst because the level of the water reached the floor of my trailer."

The waters may rise again during high tide around 9 p.m., Razetti said. "But we're going to watch it very closely," he said.

Whether the flooding was caused by damage to a levee is unclear, Razetti said. Engineers still have not been able to determine the cause of the rapid flooding Monday night.

"A lot of it is still covered by water, s you can't even really look at it," he said.
